The session began with Mark answering questions around the crucial role of different actors - varying from consumers to urban areas - in curbing climate change and securing a future based on a low carbon economy. Spotlighting the scale of the climate challenge and importance of renewables in addressing it, Mark stressed key barriers to the acceleration of clean energy adoption across the world.

When asked how he feels about the prospects for our planet, Mark said that on both a professional and personal level he is "optimistic", but emphasized that renewables must be embedded deeply into our energy infrastructure across all economies and industries in order to have a real impact towards achieving a safer future.

@TrillionFund@ClimateGroup renewables need to be at core of future energy not "nice to have" add-on - capacity exists, just need will

Questioned about the true power of public platforms such as social media, Mark underlined how critical mass movements can spur businesses and governments to act. But despite its potential influence, much progress is still to be made in a mainstream climate movement, as highlighted by BT's Chief Sustainability Officer who asked Mark his thoughts on why there has been no mass change in public opinion and action around climate change.

Turning the focus to the bi-partisan politics of climate change, Mark highlighted 'odd moments' of cross-party consensus such as in the UK 3 years ago, but largely critisized the perception of the climate change dialogue for not being seen as a source of future prosperity and jobs - as it should be.

@stewartboyle4 we need to show that action on CC meets all people's aspirations - not about sacrifice but about prosperity and security

Concluding by looking at key actions government leaders could take to accelerate a clean revolution, Mark was also keen to highlight progress that has been made over the past 10 years, a point that will be shared at The Climate Group's event in London this coming Monday.
